AvaSpire® AV-621 is an unreinforced polyaryletherketone (PAEK) that offers improved ductility and impact strength relative to PEEK while retaining most of the key performance attributes of PEEK. The AV-621 grade is the low melt flow (higher molecular weight) analogue of the medium flow grade AvaSpire® AV-651 that is tailored primarily for injection molding applications as well as film extrusion. AvaSpire® AV-621 resin is suited for a variety of processing methods including compression molding, stock shape extrusion, as well as injection molding. AV-621 has been formulated for applications requiring a balance of chemical resistance and mechanical strength along with good part aesthetics, thereby bridging the performance gaps within the ultra polymers space. These and other properties make this resin well-suited for applications in healthcare, transportation, semiconductor, electronics, chemical processing, and other industries. AvaSpire® AV-621 is easily fabricated using conventional thermoplastic melt processing techniques and standard equipment. The resin has a uniform opaque appearance with a beige color similar to that of PEEK. 

AvaSpire® AV-630 is an unreinforced polyaryletherketone (PAEK) developed as an alternative to low melt flow PEEK for the extrusion of ultra-thin films. Films with thicknesses as low as 0.2 mils (5 microns) can be successfully melt extruded out of AV-630 using conventional thermoplastics film extrusion equipment.
Films of AV-630 offer certain performance advantages over comparable PEEK film. These include improved toughness and ductility, a higher retention of mechanical integrity at temperatures above 150°C, better acceptance of adhesives and improved flame propagation resistance properties. Ultra-thin films (<15 microns thick) also exhibit a more flexible, less crinkly feel than that of PEEK films at comparable thicknesses. 
Sub-mil thick films produced from AV-630 can be utilized in a wide range of industrial applications. Typical applications include capacitors, electrical insulation, flexible circuitry substrates, composite film layers, specialty laminates, good flexibilities, liners and aerospace films, such a thermal acoustical insulation blanket bagging materials.

AvaSpire® AV-651 is an unreinforced polyaryletherketone (PAEK) that offers more ductility and impact strength than PEEK, with higher chemical and environmental stress cracking resistance than AvaSpire® AV-650. It has been specifically formulated for applications requiring a balance of chemical resistance and mechanical strength along with good part aesthetics, bridging the performance gaps within the ultra polymers space. 
These properties make it well-suited for applications in healthcare, transportation, electronics, chemical processing and other industrial uses. AvaSpire® AV-651 can be easily processed by typical injection molding and extrusion methods using conventional processing equipment. 

AvaSpire® AV-651 CF30 is a 30% carbon fiber reinforced version of AvaSpire® AV-651. This formulation offers some advantages relative to 30% carbon fiber reinforced PEEK which include better dimensional stability and warp resistance during injection molding. The AV-651 CF30 grade offers the highest strength, stiffness, and fatigue resistance of any AV-651-based grade. Furthermore, this resin generally retains most of the desirable ultra-performance attributes of carbon fiber reinforced PEEK. Those attributes include chemical resistance, fatigue resistance, and long term thermal oxidative stability.
The excellent balance of properties of AV-651 CF30 makes this grade well suited for a broad range of applications across a number of industries including healthcare, transportation, electronics, oil and gas, and chemical processing.
 This resin can be easily melt processed by injection molding using standard equipment. The melt processing behavior of AV-651 CF30 is overall very similar to that of 30% CF reinforced PEEK. While the resin can also be extruded, the lower melt flow AV-621 CF30 grade is considered more suited for extrusion applications while offering the same property profile as AV-651 CF30.

AvaSpire® AV-651 GF30 is a 30% glass fiber reinforced polyaryletherketone (PAEK) that has been specifically formulated to provide higher mechanical strength and stiffness than unfilled AV-651 resin. This resin offers chemical resistance nearly equivalent to glass fiber-reinforced PEEK in most chemicals, with a lower heat deflection temperature. These properties make it well suited for applications in healthcare, transportation, electronics, chemical processing and other industrial uses.
